TEMPE, AZ - Folks from around the country are flooding into the Valley this weekend to compete in Ironman Arizona on Sunday.
Many competitors have had to overcome obstacles to get here and Bill Gilbertson is one of them. He first started competing in triathlons when he weighed 400 pounds.
Now 120 pounds lighter, Gilbertson is set to do his third Ironman. However, it's been a long journey to get to this point. He had to drop out of his first Ironman after injuring himself on the bike ride.
On his second attempt it took him more than 17 hours to finish the course which meant he wasn't an "official" finisher.
This time around he said he has a new level of confidence and there's nothing, including his weight, holding him back.
Through his Ironman competitions Gilbertson has raised more than $10,000 for Chances for Children, a charity that supports programs to keep kids active and healthy.
